To all whom it may Be it known that a citizen of the United concern I, FRANK S. VnunoNn, States, residing at J oliet, in the county of Will and State of Illinois,

The invention will be best. understood from a consideration of the following taken in tailed description drawings the accompanying this specification,

deconnection with forming part of with the understanding that the invention is not confined to any strict conformity to the showing of the drawings, but may be changed and modified so long as such mark no material departure changes and modifications from the salient features of the invention as expressed in the appended claim.

In the drawings:

Figure 1 is a perspective tially extended fly screen,

Fig. 2 is a section on Fig. 1,

Fig. 3 is a screen shown in Fig. 1, h

Fig. 4 is a detail perspe view of a parthe line 2-2 of longitudinal section of the fly ctive of a slide structure employed in the screen.

In the drawings screen frames there are shown two A and B which may be substantially alike and one slidable with relation to the other so that the the combined sashes may contracted as desired.

Each frame is and comprises an end rail and a bottom rail 3. The greater thickness than the area covered by be extended or of substantially U-shape 1., a top rail 2, end rails are'of top,.and bottom to the top and bottom rails of the other frame. The top and'bot 7 tom rails of one frame are oppositely d1s posed with respect to the top and bottom rails of the other frame.

The top and bottom rail of each frame is provided with a longitudinally extending slot 4 and the slots 4 are so setup that the slots of one frame Wlll register with the slots of the other frame. The slots are positioned between the upper and lower edges of a rail and extend from a point re moved from the V at a point removed from the inner end of a rail.

The inner edge of each end rail 1 is formed with a lengthwise extending groove the lower edge of eachtop. rail 2 is provided with a longitudinally extending groove 5" and the upperedge of eachbottom rail is formed with a longitudinally extending groove 5. The grooves in the top and bottom rails register with the grooves in the end rails, and the said grooves 5, 5' and 5" of each frame have extended therein a foraminous sheet 6, such as metallic screen cloth and which is of such size as to terminate at a point removed from the free ends of the top and bottom rails of the frame.

The screen frames are held to ether by slidable clip structures or plates ing through registering slots 4 of the top and bottom legs.
